Murraysmith Presentation on WSMP

SUB General Manager Jeff Nelson introduced Michael McKillip and Brian Ginter, consultants with Murraysmith, and noted that the consultant team provided a copy of their presentation for both SUB and Rainbow’s Boards to review prior to this meeting. He then invited the consultants to begin their presentation.

Referring to their presentation, Water System Master Plan – Springfield Utility Board, Rainbow Water District (Exhibit A), Michael McKillip and Brian Ginter spent about 30 minutes sharing an overview on the Water System Master Plan.

The state requires that master plans shall evaluate the needs of the water system for at least a 20 year period and that it complies with the requirements as defined in Oregon Administrative Rules (OAR) 333- 061-0060.

  • The previous Water System Master Plan was prepared in 2010; and this update is necessary for SUB and Rainbow to incorporate current conditions and identify capital projects necessary to maintain supply capacity and support the development projected to occur in the Springfield Urban Growth Boundary (UGB).
  • Plan elements include: description of existing facilities, establish the projected water demand in the 20-year planning period, establish the desired level of service goals and performance criteria, identify deficiencies and develop solutions, meet State of Oregon resiliency planning goals, and describe financing options that could pay for the listed projects.
  • The existing system includes SUB’s Willamette Wellfield Slow Sand Filter Plant, 8 storage reservoirs, 12 pump stations, 24 SUB wells, 8 Rainbow wells, and 3 wells jointly owned by SUB and Rainbow.
  • Current peak demand flow is determined to be 28.19 million gallons per day (mgd) with 22.24 mgd considered the reliable capacity. Maximum day water demand in 2040 (the end of the planning period) is expected to reach 24.6 mgd and 27.3 mgd at full build-out in the UGB.
  • Distribution system planning analysis included an evaluation of storage volume needs, fire flows and fire hydrant spacing. Hydraulic modeling considered transmission system improvements and pending projects to improve connectivity of first level reservoirs.
  • A seismic resilience evaluation was included as recommended by the Oregon Resilience Plan, assessing water infrastructure vulnerability to seismic risks and providing recommendations for a 50-year mitigation plan to improve resilience. Pipe material, joint type, installation and geologic conditions were incorporated into a pipeline fragility analysis. A review of the 2014 storage reservoir seismic reservoir evaluation contributed to the assessment.
  • The plan identified backbone piping important to maintain service to select critical facilities.
  • Recommended Capital Improvement Programs (CIP) were developed with 20-year total costs projected at $159,926,617 for SUB and $20,534,000 for Rainbow. The CIP includes estimated project costs and approximate construction timeframes for a range of listed projects.
  • CIP funding will be supported by a financial analysis provided by the Galardi-Rothstein Group, an update to System Development Charges, and an evaluation of water rates.
  • Following review and approval by the SUB and Rainbow Boards, the draft Water System Master Plan will be submitted to the Oregon Health Authority for final review leading to adoption.

Q&A Period

RWD and SUB Board members alternated in asking clarifying questions pertaining to the Water System Master Plan. This discussion included topics on water needs as related to Cascadia events, climate change, water system performance, infrastructure improvement, and coordinated efforts in long term planning.


Board President Allocco gave closing comments and adjourned the meeting for Rainbow Water District at 7:20 p.m. Vice-Chair Scherer shared closing comments and adjourned the meeting for Springfield Utility Board at 7:22 p.m.
